We stock the most reliable thermocouple wire and cable for optimal performance in an array of configurations. Made to stringent material standards, our thermocouple-grade wire offers the top choices in alloy wire type, size, protection and insulation.A thermocouple wire is a duplex wire, meaning two insulated wires of different materials are in one sheath. Each ANSI thermocouple type is comprised of a specific wire pairing that generates signals. For example, Type J cable combines iron and constantan wires. Other commonly deployed wiring is identified as E, K, and T. Duplex insulation is color coded according to ANSI MC 96.1-1982. Choose the insulation materials that deliver industrial features – from high temperature capability to optimal noise rejection. Materials are dictated by the thermocouple type. The K type Thermocouple and J type are the most popularly used types. Durable fiberglass is used in general and high temperature applications. Economical PVC-insulated wire offers flexibility and affordability. Our most popular insulated wiring categories include:
- Fiberglass: Features braided fiberglass insulation for intense heat protection, with maximum temperature of 900°F and a stainless steel over-braid option.
- FEP (Teflon): Insulation for up to 400°F max temperature. Moisture resistance available.
- PVC: Polymer insulation for up to 220°F.
- Multi-conductor cable
